CHARLES H. IVES, OF LITTLE FALLS, NE\V YORK.

CAR-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 460,798, dated October 6, 1891.

Application filed January 28, 1891. Serial No. 379,396- (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. IVES, a citizen of the United States of America, residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and usefulImprovements in Freight-Oar-Door Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in car-door locks, and is especially designed for employment upon cars having sliding doors, such as freight-cars.

The leading object of my invention is the provision of a lock for the purpose named which will prevent thieves or others from unlawfully entering the ears while they are in motion or when stopped. The looks at present used upon the cars are defective for the purpose, in that persons can while the cars are in motion tamper with the lock and release the same and enter the cars; but mylock will prevent entrance to the cars by unlawful methods.

A further object of my invention is the provision of a lock of the character and for the purpose mentioned which can be applied to freight-ears at a small expense, which will be of durable construction, and easy and effective of operation.

To attain the desired objects the invention consists of a locking lever or levers and tumbling or looking rods disposed beneath the ears, whereby they cannot be tampered with.

The invention further consists of lockingrods journaled to the bottom of the car and having the outer end adapted to engage and lock the doors and their inner ends secured by a lever or levers, and means for securing said lever or levers.

The invention further consists in certain features of construction and combinations of parts, whereby an efficient and useful lock is provided, substantially as herein illustrated, described, and then specifically defined and distinguished by the claims.-

In order that the construction, operation, and advantages of my improved lock may be readily understood, I have illustrated the same in the accompanying drawings, in which- Figure 1. represents a plan view of the bottom of a car with my improved lock applied.

Fig. 2 represents an elevation of a car with my lock applied, the parts being in the position they assume when locked. Fig. 3 repre sents a similar view, the parts being in the position they assume when open or unlocked. Figse to 9 represent detail views of the parts of the lock.

Referring by numerals to the drawings, in which similar numerals denote corfesponding parts in the several views, the numeral 1 denotes the car, or as much thereof as is neces sary to illustrate the application of my lock, having the usual sliding doors 2, which ride on the brackets 3, all of which are of the wellknown or of any desired construction. On the bottom of the car are the longitudinal parallel bars or rails i,in the two central ones of which is mounted a shaft or pin 5, bearings therefor being secured to said rails, and on this pin or shaft is mounted a locking-lever G.

I would here state that I show and prefer to use but one of the locking-levers, as one performs the functions in a perfect manner and is less expensive than using two, although I may use two if I desire. Thislever is curved at the pivotal end and is made large at the free end-that is, the free end is weightedwhereby the lever is normally held down, the purpose of which will appear. If it is desired to lock the lever down, I employ a bar or arm 7, which passes through an opening in the plate 8 and is secured by a suitable lock 9, preferably a padlock. The lever is also provided with the recesses lO-one on each sidcand the depression 11 for a purpose to be explained. The recesses or kerfs 10 are arranged one on each side of the lever, and are inclined inward, as shown, and the groove or depression 11 is arranged transversely on the under face of the lever.

In the rails on the bottom of the car are j ourn aled the tumbling-rods 12, the inner ends of which are formed with the crank 13, having the toe 14, and the outer ends of the rods are provided with the too or looking projection 15, which is adapted when the doors are closed to be drawn outwardly and through the plate or keeper 16, secured to the doors of the car, the doors being formed with kerfs 17 to admit the toe, and said toe being beveled or smoothed to press firmly against the keeper-plate on the car-doors to securely lock said doors. Then the doors are locked, the cranks have the toe thereon resting in the transverse groove or depression 11' of the lever, and the toe 011 the outer ends of the rods is in engagement with the keeper-plates on the car-doors, asseen in Figs. 1 and 2, and when the doors are unlocked the toes on the cranks rest in the recesses or kerfs of the lever and the toes 011 the outer ends of the rods are out of engagement with the keeper- 'plate.

When it is desired to secure the car, the doors are closed, the rods are turned by inserting a key 18 into an opening in the outer ends of the rods,which causes the toes on the outer ends of the rods to engage the lockingplate on the car-door and the cranks on the inner ends of the rods to rest in the transverse groove or depression 11 in the lever, thus securing the rods and locking the doors, and the weight of the lever holds the rods in locked position, or the lever may be locked down; and to unlock the doors it is only necessary to turn the rods in the reverse direction, which releases the toes on the outer ends of the rods. Then push the rods inward, which causes the toes on the inner ends to rest in the recesses 10 ot' the lever, as shown by dotted lines in Fig. 1. It will thus be seen that by turning the rods in one direction the toes 14 thereof are caused to enter the groove 11 of the lever, which causes the locking projections 15 to engage the keeper l6, and the weight of the lever holds the rods in this position, thus locking the doors; and when the rods are turned in the opposite direction the projections 15 are released from the keepers 16 and the cranks 13 are brought opposite the inclined recesses or kerfs 10 of the lever, and it is then only necessary to push the rods inward and force the cranks 13 into the recesses 10, which moves the outer ends of the 'rods out of the path of the doors, allowing said doors to be opened, as is evident.

From the foregoing it will be seen that the lock is operated by turning the rods in opposite directions and that the lock is easy and efficient in operation, is of simple and inexpensive construciion, and can be easily applied to cars.

l Iaving fully claim- 1. In a oar-doorlock, the coinbination,with the car and the doors thereof, of a lever pivoted at one end to the under side of the car, and rods rotatably mounted in the car'and having cranks on their inner ends, formed with toes for engaging the other end of said lever, and toes 011 their outer ends for engaging the doorkeepers, substantially as and for the purpose described.

2. In a car-door lock, the combination, with the car and the doors thereof provided with openings and keepers at the lower edges, of a lever pivoted to the under side of the car and having a transverse groove and recesses, as described,rods pivoted in the car and having toes for engaging the groove, and cranks for engaging the recesses of the lever and at their outer ends provided with toes for engaging the keepers on the car-doors, substantially as described. 7

In a car-doorlock, the combination,with

. ,6 described my invention, I

the car and the doors having keepers, of the weighted lever pivoted to the under side of the car and having the groove and recesses, as described, the rods pivoted to the car and having their inner ends adapted to engage the groove and recesses of the lever and their outer ends adapted to engage the keepers on the doors, and a lock for securing the lever, substantially as described. V In testimony whereof I affix mysignature in. presence of two witnesses.
